IMPROVEMENT IN STREET-SPRINKLERS.

Specification forming part of Letters Patent No. 53,557, dated April 3, 1866.

To all whom it may conce/Mz.-

Be it known that I, L. E. BANGROFI, ofthe city and county of Vorcester, and State of Massachusetts, have invented certain new and useful Improvements in Street-Sprinklers; and I do hereby declare that the following' is a full, clear, and exact description of the saine, reference being had tothe accompanying drawings, forming a part otl this specification, in which- Figure l represents a perspective view of my improved street-sprinkler, and Fig. 2 represents a front view.

In the drawings, A represents the reservoir or water-receptacle, which is ot' circular form from a up and over to b and tlat on the bottom. The water-receptacle A rests upon a frame composed of the longitudinal timbers B and C and cross-timbers D D D D.

E is the sprinkling-chamber, which is supported by stay-rods c c c c from the projecting ends of thetinibersB and C. The water passes to the sprinkling-chamber throughthe branchpipes F' F' Fof pipe F.

Gr is the turret or dome through which the water is passed to ll the receptacle A. II is the operators seat, and I his toot-board. d is a valve-rod connected with slide e, by means of which the driver can open and close the valve to let on or shut oft' the water from pipe F.

The cross-timbers extend by or project at each side, so that springs J J can be applied to support the water-receptacle A outside ot' the latter, as fully indicated in the'drawings, thus enabling the same to be supported in a secure and easy manner. The trout set of springs, J', one on each side ofthe receptacle A, rests upon the rocker timber or piece K', which is to be secured to the axle ofthe wagon or running part.

Water-sprinklers for street use as heretofore constructed have been very objectionable, one ot the most objectionable features being a constant liability to leak, whereby the running-gear of the wagon, upon which the waterreceptacle is mounted, soon rots and breaks, thus involving a constant expense for repairs. Again, with the box form of water receptacle or reservoir, the motion of t-he water in pass ing over pavements and uneven streets is so violent that the sides, ends, and top of the reservoir soon give out.

By the form and mode ot construction ot' my since if the joints begin to loosen at all they can be quickly tightened up by the nutsf on the clamping-bands L, which pass around the water-receptacle A and thence through the ends of the cross-pieces D, to receive the washers g and nuts f. The top ofthe water-receptacle A being arched and tight the water does not have the injurious effect upon it as it would it the sides were perpendicular and the top dat.

The-carriage or wheel part, upon which the reservoir A is mounted, can be turned quite short round, since the front wheels may be turned in under the reservoir.

The body A can he made of strips tongued and grooved or with plain joints. It willbe observed that the form is such that by turning up the nuts fthe bottoni M is tightened as well as the arched or circular part of A.

The bed-piece I( is attached to the rear axle otl the wagon.

Havin g described my improved streetsprinkler, what l claim therein as my invenV tion, and desire to secure by Letters Patent, 1s-

l\zlaking the upper part of the water-reservoir A circular and the bottoni flat, in combination with the use of lthe clamping-bands L and ti gh tening-u nts j'.
